CATTLE-GUARD.-

Specification of Letters Patent.

. Patented June 6, 1916.

Application filed November 10, 1913, Serial No. 800,233. 1 Renewed November 13, 1915. Serial No. 61,441.

T 0 all whom it may concern:

Be it known that I, JONAS PEHRSON, of the village of Tyndall, in the'Province of Manitoba, Canada, have invented certain new and useful Improvements in Cattle- Guards, of which the following is the specification.

The invention relates to an improvement in cattle guards and the object of the invention is to provide an inexpensive, durable, easily installed guard which when applied will effectively prevent cattle from wandering on'the rails at the points where the guard is installed it being understood that they are installed preferably at the opposite sides of crossings.

With the above object in View the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claim.

Figure 1 represents a plan view of my complete device installed. Fig. 2 represents a longitudinal sectional view through the same. Fig. 3 represents an enlarged detailed interior view of a portion of the frame showing the manner in which the top and bottom members are held together. Fig. t is an enlarged detailed side view of one of the star shaped members.

In the drawing like characters of refer ence indicate corresponding parts in each figure.

1 represents a substantially rectangular frame formed from end beams 2 and 3 and pairs of-top and bottom sidepieces 4E and 5, the side pieces 5 being permanently secured to the end pieces, while members 4 are releasably secured to the pieces 5 in a manner later described. I

The frame is inserted between the ordinary railway tracks A and B and is secured to the ordinary ties 6 in any suitable manner such as by spiking.

Guard plates 7 and 8 are secured to the end beams 2 and 3 and to the adjoining ties. These guard plates form in reality an approach to the guard.

The top members 4 are secured to those 5 by means of clamps 9, these clamps having their upper ends hooked'over the upper edges of the pieces l and thelr lower'ends passing to the side of the side pieces 5, the said lower ends being slotted as indicated at 10 to receive cranks 11 carried by the bottom piece. In applying these clamps to hold the top and bottom pieces together the cranks are first turned in a vertical direction so as to allow them to enter and pass throughthe slots 10 formed in the clamps.

The upper ends of the clamps are clipped consequently effect the fastening of the top w pieces to the bottom pieces.

12 are a number of similar paralleled cross rods carried by the frameand having their ends received within. suitable bearings 13 formed in the adjoining edges of the side pieces 4 and 5.

It will be understood that the bearings above referred to are formed by partially boring out the side pieces to formpairs of opposing sockets.

The cross rods are placed in position prior to clamping the top piece to the bottom piece.

14 are sets of similar star shaped members threaded on the rods and spaced apart by inserted sleeves 15 carried by the rods. lhe sleeves are arranged so that the various sets ofstars are staggered.

It will be noticed that I have made the members l t with seven points.

Upon an animal attempting to pass along the track where the device is installed its hoofs or feet will be impinged on the points of the star shaped members and he will quickly withdraw, the reason of which is clearly apparent.

It will be understood of course that where the device is installed at a crossing a fence will need to be built to prevent the animal from passing to the side of the track. No such fence has been shown in the drawing as this is customary practice.

' If any of the parts shouldbecome damaged through continued use it can be readily renewed by releasing the cranks and removing the clamps, this action allowing the top side pieces to be taken off and the rods to be removed.

What I claim as my invention is A cattle guard comprising a substantially rectangular frame formed from end pieces and pairs of top and bottom side pieces, the bottom side pieces being permanently secured to the end pieces, clamps having one end secured to one side of said bottom side pieces and having a slot adjacent the free ends, cranks secured to the opposite sides of said side pieces, said clamps being adapted to clip over the upper'side pieces, the slots in the free ends of said clamps being adapted to receive said cranks, said pairs of side pieces being formed With opposing bearings, paralleled cross rods contained Within the frame and having their ends received Within the bearings presented by the side July, 1913. JONAS PEHRSON.
